cayuse
noun
1.
Origin
Named after the Cayuse tribe of the Pacific Northwest. However, the etymology of this tribe name is unknown; it may be an exonym, and may in fact come from Spanish caballo (“horse”), which is the source of the word for horse in many Native American languages of western North America.
